In a series of six consecutive even numbers, the sum of the second and sixth numbers is 24. What is the fourth number?

In a series of six consecutive even numbers, the sum of the second and sixth numbers is 24. What is the fourth number?

A. 8
B. 12
C. 6
D. 14
E. None of these
Explanation:
Let the numbers be x, x + 2, x + 4, x + 6, x + 8 and x + 10.
Given (x + 2) + (x + 10) = 24
=> 2x + 12 = 24 => x = 6
The fourth number = x + 6 = 6 + 6 = 12.

A man buys an article for 10% less than its value and sells it for 10% more than its value. His gain or loss percent is:________?

A man buys an article for 10% less than its value and sells it for 10% more than its value. His gain or loss percent is:________?

A. no profit, no loss
B. 20% profit
C. less than 20% profit
D. more than 20% profit
Explanation:
Let the article be worth Rs. x.
C.P. 90% of Rs. x = Rs. 9x/10
S.P. = 110% of Rs. x = Rs. 11x/10
Gain = (11x/10 – 9x/10) = Rs. x/5
Gain % = x/5 * 10/9x * 100 = 22 2/9 % > 20%

The tank full of petrol in Haroon’s motorcycle lasts for 10 days, if he starts using 25% more every day for how many days will the tank full of petrol last?

The tank full of petrol in Haroon’s motorcycle lasts for 10 days, if he starts using 25% more every day for how many days will the tank full of petrol last?

A. 5days
B. 6days
C. 7days
D. 8days
Explanation:
Let us assume that Arun uses X units of petrol everyday.
So the amount of petrol in the tank when it is fuel will be 10X.
If he started using 25% more petrol every day, then the amount of petrol he how uses everyday will be
X (1 +25/100) =1.25x
Therefore, number of days his petrol will how last = Amount of petrol in tank / amount of petrol used everyday = 10x/1.25x = 10/1.25 = 8 Days

The area of the square formed on the diagonal of a rectangle as its side is 108 1/3 % more than the area of the rectangle. If the perimeter of the rectangle is 28 units, find the difference between the sides of the rectangle?

The area of the square formed on the diagonal of a rectangle as its side is 108 1/3 % more than the area of the rectangle. If the perimeter of the rectangle is 28 units, find the difference between the sides of the rectangle?

A. 8
B. 12
C. 6
D. 2
Let the sides of the rectangle be l and b respectively.
From the given data,
(√l2 + b2) = (1 + 108 1/3 %)lb
=> l2 + b2 = (1 + 325/3 * 1/100)lb
= (1 + 13/12)lb
= 25/12 lb
=> (l2 + b2)/lb = 25/12
12(l2 + b2) = 25lb
Adding 24lb on both sides
12l2 + 12b2 + 24lb = 49lb
12(l2 + b2 + 2lb) = 49lb
but 2(l + b) = 28 => l + b = 14
12(l + b)2 = 49lb
=> 12(14)2 = 49lb
=> lb = 48
Since l + b = 14, l = 8 and b = 6
l – b = 8 – 6 = 2m.
